Background technology
At present, existing two-colour fluviograph major defect is, the big water temperature rapid heat dissipation in it of two-colour fluviograph main body, in main body, water temperature is the biggest by surrounding environment influence simultaneously, cause in water-level gauge water temperature in water temperature drum to be far below, so the density of water in the density of water is higher than drum in two-colour fluviograph main body, can learn according to Communicating device principle, liquid level in tested liquid level drum to be far below in measuring cylinder, this deviation can be along with the rising of drum pressure, the rising of temperature becomes increasing, thus cause operations staff can not judge water level height in drum from the liquid level of water-level gauge, in turn result in potential safety hazard.
Utility model content
The purpose of this utility model is, devises the double-colored level measurement device of high-resolution of a kind of band heat tracing circulation, solves the problem that level measuring deviation that existing two-colour fluviograph causes because of water temperature in main body is big far below water temperature in drum, and accuracy of measurement is high.
The technical solution of the utility model is:
A kind of high-resolution double-colored level measurement device of band heat tracing circulation, including water-level gauge housing, described water-level gauge housing is provided with form gland, it is provided with water-level gauge main body in described water-level gauge housing, the bottom of described water-level gauge housing is provided with condenser, bottom is provided with heat tracing circulation pipe, the upper end of described water-level gauge housing is connected with vapour side valve door by vapour side joint pipe, the lower end of described water-level gauge housing is connected by water side joint Guan Yushui side valve door, being connected by balance pipe between described vapour side valve Men Yushui side valve door phase, described water side valve door is connected with sewage draining valve pipeline；Wherein, heat tracing part mainly embodies in water-level gauge main body, and described water-level gauge main body is provided with circulation heat tracing hole and form observation port, and the both ends in described circulation heat tracing hole are provided with plug, it is provided with isolation plug between described circulation heat tracing hole and form observation port, makes the two separate and do not interfere with each other；Described water-level gauge housing is connected with heat tracing circulation pipe by heat tracing joint and four-way connection, utilizes saturated vapor to heat to water-level gauge main body.
Further, described water-level gauge main body uses open grain structure.
After being connected with drum, saturated vapor passes through heat tracing hole and heat tracing circulation pipe, and water-level gauge main body utilizes the heat of saturated vapor to heat to the water in water-level gauge form hole always in the process.Water-level gauge main body utilizes saturated vapor to heat to the water in water-level gauge form hole, allows in water-level gauge water temperature close to water temperature in drum.
Utilize the saturated vapor in drum that water-level gauge main body is heated when normal work, the most farthest decrease that water temperature in water-level gauge main body is affected by the external environment and the temperature that produces reduces, in making water-level gauge main body observation port, water temperature is always close to water temperature in drum, therefore accuracy of measurement is high.
The utility model has the advantage of: solve the problem that level measuring deviation that existing two-colour fluviograph causes because of water temperature in main body is big far below water temperature in drum, accuracy of measurement is high, reduce the properly functioning of the potential safety hazard brought because drum level measurement is inaccurate, beneficially boiler.
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
